T0 all whom t may concern :n

Be it known that I, HARRY J. Permits, a citizen of the United States, residing .at Grand Rapids, in the county of Kent and State of Michigan, have invent-ed new and useful linproveinents in Reversible Rotary Driving Devices, of which the following is a specification.

My present invention relates to reversible rotary driving devices, and its object is to provide a device of that character in which Vthe driving and the driven rotatable shafts may be coupled together to rotate as one shaft in the regular operation of the mechanisin, .e. when the driving is in the usual direction; and also, to provide such a device in which the principal operating parts may be readily removed from such shafts and replaced thereon by movement in the shafts axial directiongand also, to provide a reversing gear-carrying cage which niay be readily assembled with and reinovedfroin the other operative parts of the mechanism; and also, to provide other and subsidiary associated devices; and also to provide the foregoing or certain thereof in various coinbinations; and also, to provide a reversible rotary driving` device iinproved in various particulars hereinafter appearing. These objects are attained by, and the invention. finds a preferable embodiment in. structure hereinafter described, and illustrated by the accompanying drawingsy in which Figure l is a side yview of iny device: Fig. 2 is a forward end new-thereof, one side being broken away: Fig. 3 is a vertical axial seetion'of the saine, certain parts being reinoved: Fig. d is a transaxial sectional view of the saine on a plane correspondini,T with line d-#l of Fig. 3, and showing iu face view, one of the frictioiial clutch disks: lfig. 5 is a like view of the de *ice on a plane corresponding with line 5-5 of Fig. 3, and showing in face view one of the frictional clutch disks which coperatie with those like that shown in Fig. l: Fig. 6 is u transeixial sectional view of the reversing gear-carrying cage oii a. plane corresponding with line 6*@ of Fig. 7; and with line G G of ifjig. 3: Fig. 7 is un axial sectional view of the suine on a plane corresponding with line rim-7 of (S: 8 is un axial sectional vier.' of il operative parts of a variant te, on a plane corresponding n l fie; l is a rightn vice shown in Fig.

ticn however, .c. to back the boat, these shafts rotate in contrary directions as heren inafter explained. These ends are eii'ected by the following mechanism: A hollow drinn 5, concentric with and surrounding` the shafts is adapted to rotate independently thereof, as on bushings G: lt is also adapted to couple by the following means the shafts together, that they may rotate as one: Keys 7 and keyways S on the interior wall of thel druin, and resembling the teeth of an internal `ajear, interlock with Correspendingr keyways 9 and keys 10 of annular friction clutch disks il surrounding' and concentric with the shafts: alternately disposed between Athese disks are coperatin` clutch disks l2 having keyways 14 and keys 13 interlocking, in case of soiiie such disksas those to the right hand side of Fig. B--with correspending gear teeth il? (and their intervals) carried by the driving shaft; and in case of the other such disks l.Q,-as,those to the 'j eft ol' said hgure-WMh similar teeth l5 (and their intervals) carried by the driven shaft. '.lhese clutch disks are frictioiially clamped `together side to sido, in order to couple the shafts to euch other, b v suitable nie ns, prete .ely a hand lever lh statiouarilv fulcruniif l? and having a suitable fork 1 e.,. io; the lirooved coll. lll slidnble on t e shaft: lo i collar piroted as t arin @lof a toggle relie other arm ivotally connected :it 33% ai the arin f' 24, in el'ect on the drum, i'. e. on the drums screw collar 25. The arm 22 is a lever hava cam 26 engaging a plunger 27 slidab e on the drum and whose inner end engages the outmost disk 12. When the hand lever is pushed toward the right hand side of Fig. 1, it forces through the parts above described the disks and the gear-carrying cage 28 to the right of Figs. l and 2, and against the inner right-hand end, Wall of the drum 5, thus rictionally clamping such disks together, whereby their clutch operation is effected. The collar 25 is screwthreaded on the drum, as shown and is provided With a spring-pressed catch 29 adapted to enter a suitable oriiice 30 in the end face of the drum, so that by turning the collar 25 the degree of the plungers pressure may be regulated.

The engagement of the clutch disks being released, the rotary movement of the driven shaft is reversed by the following devices: A gear-carrying cage 28 is interposed between the clutch disks surrounding the driving shaft and those surrounding the driven shaft, as particularly shown in Fig. 3. This cage comprises parallel annular disk portions 3l spaced a art and connected by a web 84, and provi ed circumferentially with keys 32 and keyways 33 similar to those of the disks 11 and adapted to similarly inter lock with the corresponding keyways 8 and keys 7 of the drum. On a spindle 1.00 eirtending betvv een and carried by the disk portions 31 rotates the intermediate stepped gear 35 Whose larger gear 36 meshes with and is'driven by the gear teeth 37 of the driving shaft, and whose smaller gear 38 meshes with and drives the idler gear 39, pivoted on the cages disk-portions, which ear meshes with the gear teeth 15 carried Ey the driven shaft. The drinn is secured against rotary movement during the reverse driving of the propeller shaft by a frictionally holding band 40 stationarily fas.

tened as to the engine bed plate, and tightened by suitable means, as a plunger Lil; slidable on one end of the split band, as by a link 42 pivoted thereto and to the hand lever 1G: ln moving this plunger in the direction toward the left-hand of Fig. 1, it engages as by its shoulder 4:3 the lever arm 44 pivoted on the other end of the band, thus drawing the bands ends toward each other and clamping the drinn by the band: the reverse motion ot' the plunger releases the arm 44 and loosens the band. ltxyrill be seen that by removing the druins'hepad 46 the disks and cage may be readiiy withdrawn, being slidable along thclo ys of the drum and the gear teeth of the siafts.

In the variant form of my invention shown in F 8 and 9, there is an inner drum 47 keyed to thc driven shaft and inclosing the disks which surround the driving shaft and the intermediate reversing gears 49 which are driven by the gear teeth 50 of the driving shaft and which drive the drums internal gcar 51: there is also an outer drinn inclosing thc inner drum 7;; and the disks surrounding the driven shaft.

In the construction illustrated in Fig. 9 sii;

of these reversing gears i9 are shown.

`When the clamping pressure is exerted on the plunger 27, the radially-extending 7 iiange 511 is clamped between the disks on the right-hand side thereof (which surround the driving shaft) and those on the left-hand side thereof (which surround the driven shaft), and thereby the shafts r0- -tate in coupled relation as one.

In the variant form of my invention shown in Figs. and 13, the means for tightening the drum's holding band comprise a pair of levers 52, having a common fulcrum, which engage lugs at the ends of the split band: by drawing the plunger 54 toward the lcitdnxnd the ings are pressed toward each other through the slotted arms pivoted on the plunger. An adjusting screw 56 may be provided to regulate the :ict-ion of the levers The plunger 5l through suitable connecting parts 60 slides the collar 19 to engage or release the clutch disks. A suitable casing 57 may be provided.
